What are the Challenges in Using Biological Samples?
Several challenges arise when using biological samples in epidemiological studies:
Degradation: Biological samples can degrade over time, affecting the reliability of the results. Variability: Inter-individual variability can complicate data analysis and interpretation. Contamination: Samples can be contaminated during collection, storage, or analysis. Cost: The collection, storage, and analysis of biological samples can be expensive.
